摘要

Graphene aerogel/PVDF (GA/PVDF) composites with a three-dimensional structure were prepared using a vacuum-assisted impregnation process. The phase structure, morphology and piezoelectric properties have been systematically studied. The results show that GA/PVDF composites have good piezoelectric output characteristics and can provide corresponding feedback according to the magnitude and frequency of the acting force. When the PVDF concentration is 80 mg/mL, the GA/PVDF composite reaches the highest piezoelectric constant (d₃₃ = 16 pC/N). The average peak output current is approximately 0.51 μA and shows good stability under repeated pressing. It is promising to apply to the field of flexible pressure sensors that can be self-powered.
